Keep the flash channel and patent breach clean. Pipe cleaners work well, work it in through the nipple threaded hole.
Get a CO2 discharger or remove the nipple and work a little 4f powder into the breach through the nipple hole, it doesn't take much.
Better than anything is to learn to keep it clean and avoid the issue from the get go.

Where is one of those for sale?
